Performance + versatility = maximum satisfaction.Racing 4is the classic trick up your sleeve because it gives that extra something, whatever the terrain.
It’s light with a responsive medium profile offering an enviable superiority andeyes fixed on performance.
Our R&D department has capitalized on experiences from developing similarrims to create this packagesuited to diverse requirements, which makes no attempt to disguise its noble pedigree.
The35 mm profileis a winning combination of great appearance and great performance. This medium profile makes all the difference on the flats at cruising speeds, but is no less excellent uphill, with agile and powerful relaunches.
RDB™ RIM DYNAMIC BALANCE
The concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the exact opposite side.
ANTI-ROTATION SYSTEM™
This new system raises the concept of spoking to a new level of performance for a road bike and triathlon wheels ( and mtb too)
The Fulcrum® engineers have redesigned the spokes and the hub housings to create a solid and unmoveable whole. The result is that the spokes
a) will never lose their initial tension, thus keeping the wheel perfectly reactive and centered
b) will remain in the position that has been studied in the wind tunnel tests to ensure the best aerodynamic penetration possible.
TRACEABILITY
A guarantee of quality
The keyword for our products is traceable.
If you find a little label attached to any Fulcrum® product, do not remove it. It will provide you a guarantee in case of an ascertained defectiveness of a production batch, and so the component needed or wheel will be traceable.
All this because, devoted to its mission, Fulcrum® demands the absolute perfection and safety for its customers.
WIDE RIM TECH
Fulcrum®’s R&D department, following requests from the competition circuit, has worked to create rims that are wider than before, about 4 mm or more than previously. This technical choice provides an ideal basis for 25/28mm tyres, the sizes currently popular.
This ensures stability, excellent handling, and superior comfort.
OVERSIZE FLANGE
The Oversize Flange was developed from the need to create a system to transmit every watt to the ground without dispersion, stiffening the wheel system where necessary, without having to add spokes or superstructures that increase weight.
The oversize flange uses physics to solve the problem. It increases dishing and enables spokes to be shortened. Doubling the spokes creates a balanced system that is excellent at transmitting torque.
